ProLipid™ 141 is a self-emulsifier from International Specialty Products (ISP). It is a lamellar system which provides benefits no other system can deliver: outstanding moisturization, skin barrier strengthening, uniform delivery of actives and product structuring. ProLipid™ 141 also provides exceptional aesthetics since high levels of oily materials feel dry and silky when delivered from this lamellar gel.

ProLipid lamellar systems are the first of their type to deliver wide pH compatibility, electrolyte tolerance, and stable rheology and temperature profiles. To achieve these benefits, a balance of components with overlapping functionalities was chosen.

ProLipid™ 141 is designed to provide a lamellar gel phase across a wide range of pHs for formulation flexibility. At acidic pH, the lecithin is the primary structuring agent. At neutral and basic pH, the fatty acids are the primary structurants. The fatty alcohols and GMS promote lamellar phase formation at all pHs.

ProLipid™ 141 lamellar gel system is a blend of well-studied and globally-approved ingredients. Each constituent has been evaluated for safety by expert committees worldwide and found to be safe and suitable across a broad range of personal care applications and use concentrations. There are no expected toxicity consequences from exposure to either the individual constituents or the blend. Although the blend has not been safety tested in animals, in clinically evaluated moisturization and barrier assessments both irritation and sensitization potential were assessed throughout the studies. None was observed. These findings have been confirmed in Human Repeated Insult Patch Testing, along with Human Phototoxicity and Photoallergy Testing.

Formulation notes:

• We recommend the use of a high shear mixer (or stick blender) or homogenizer to create emulsions with ProLipid 141 as this will optimize (reduce) the size of the droplets.
• Recommended Use Level: 3 -5%, depending on the volume and composition of the oil phase
• Recommended pH range: 3.8 - 8.0
• To optimize (increase) temperature stability: Add low levels (0.1 - 0.2% of hydrocolloids)
• Low-energy emulsification: Use gums or cellulosic thickeners, such as HEC, xanthan gum or magnesium aluminum silicate
• Preservation system: Higher levels may be required
• Materials to avoid: Dimethicone at greater than 0.5%
